LightSpeed Pure Energy technology

All LightSpeed power cord includes a special Pure Energy electronics that can effectively filter DC components that contaminate the alternating current. This results in cleaner sinusoidal alternating current, which results in more efficient operation. The special of LightSpeed Pure Energy electronics is the lighting rings of the connectors that provide a unique look to   Signature Air power cords.


LightSpeed  Signature Air has balanced Dual Hepta-core helix conductors with a total conductive cross-section of 4 AWG and reduced resistance. The appearance of the  Signature Air power cord is unusual because it has a diameter of 45 millimeters.

The dual Hepta-core pure copper increased cross-section conductors are covered with an inner PE layer, tin-plated, dense-woven pure copper shielding, synthetic polymer insulation, and a dense woven halogen-free PE outer sheath. The separate conductors are surrounded by a newly developed layer of PP Aero Fiber Tube.

The special PP Aero Fiber Tube layer approaches the dielectric constant of the air, provides protection against environmental vibrations, and ensures the adequate distance between conductors.

The LightSpeed  Signature Air has a symmetrical Balanced dual Hepta-core conductor design, providing balanced and continuous extremely high-performance power to the connected devices. The advantage of the Balanced dual Hepta-core design is the symmetry, as all wires have the same cross-section and electrical parameters, providing balanced, continuous, and extremely high performance as opposed to asymmetric cables. The asymmetric cables, such as those with double-phase conductors, can cause continuous fluctuations in alternating current due to different cross-sections and electrical parameters. Even the slightest fluctuations in the power supply can affect the stable operation of audio and video devices, as it can cause continuous noises in the sound and picture.

In addition to the advantages of symmetric design, the Balanced dual Hepta-core structure effectively reduces the skin effect, as conductors are not only composed of elementary strands but are arranged in separate groups. The cross-sectional of the dual Hepta-core separate conductors small enough to prevent the skin effect from developing, however, the overall cross-section of the conductors ensures extremely high performance and high quality.


The LightSpeed Signature Air power cord received high-quality, hand-selected polymer-composite connectors with pure copper contacts inside. The rhodium-silver coating on the outside of the contacts provides the right connection, which has measurably better electrical parameters than for example gold coating and is more resistant to environmental impacts.

In addition to the high quality of the connectors, the special look is also emphasized by the built-in LED lighting. The lighting rings of the connectors give the Signature Air model a unique look.

Signature Air power cords are built with solder-free, precision hand assembly.

Technical characteristics: Resistance: 0.0008 Ω/ft, Capacity: 40 pF/ft, Inductance: 0.2 μH/ft

LightSpeed Signature Air power cords are available with US or EU plugs and special EU/UK adapter.

Available lengths: 4 ft and custom sizes.

NOTE: To get the best quality of LightSpeed power cables, you need a “burn-in” period. After about 10-14 days of using LightSpeed cables, the sound quality becomes more life-like.
